If you are implying there's any doubt about Russian involvement in hacking aimed at the US election, there really isn't any credible doubt about that.
No one argued that ATP-28 and ATP-29 weren't Russian when they hacked the IOC and drug testing labs right after the Russian athletes were banned from the Olympic games.
Nor back in 2014[1] when the FireEye assessment was first done.
Nor in 2015, when they hacked the White House[2]
Nor during 2016, prior to the election when they were identified[3]
It's only after the election that people suddenly don't want to believe it.
